Yes. I like the question.
For one thing, I think MPs should refrain from making public the fact that they've sent me a complaint until I've received it, reacted to it, and acquainted the person who's being accused or who the contravention is claimed against with it. I think there should be some kind of prohibition against letting that information out before there have been some steps taken.
The other thing is that I'm not allowed to state my reasons for not investigating. I'm under total confidentiality. It would be very convenient to be able to explain why a particular matter was not investigated. I don't have that power either.
Those are two things.
